Title: Propeller fan with disk ring
Inventor: SEKINE YOUJI
IPC: F04D29/32
Filed: 1978-02-03
Abstract: PURPOSE: To aim at making small-sized device with low cost by devicing an improved propeller fan by which wind can be blown out in wide-angled conical form (inclined to the axial direction) without using any fixed wind tunnel or shelter.  
     CONSTITUTION: A disk ring 5 is fitted on the rear edge 4d of a blade 4 of propeller fan 2. In this case, the outside diameter E of the abovementioned ring shall remain within an extent of 0.6D W D (D=outside diameter of blade) while the inside  diameter F shall be 0.85 D or less and at the same time 0.9E or less. By this construction, the pressure difference of the radial direction becomes larger than that of  the axial direction because a centrifugal fan action produced by the disk ring 5 is  included, so that the blowout direction can be made in wide-angled conical form by  impeller's own action. And the blowing-out of the air c without touching the disk  ring 5 prevents well pressure loss and contributes to improving the blast efficiency,  and thus the total efficiency of the propeller fan 2 can be enhanced.

IPC: H01L23/495
Filed: 1984-01-23
Abstract: PURPOSE:To realize a flat package type semiconductor device free of destruction due to static surges or the like by a method wherein the segments of leads, providing external connection for a semiconductor chip, that protrude from the chip are plated while the segments remote from the chip are left exposed having poor wetting property with solder. CONSTITUTION:Lead terminals 12 for external connection protrude from a vessel 11, made of resin or ceramic, accommodating a semiconductor chip. The ends of the lead terminals 12 are connected by tie bars 13 constituting a ring- shaped metal framework. The surface of the segments of the terminals 12 near the vessel 11 are plated with a metal 14 while the segments remote from the vessel 11 remain not plated exposed the lead material of poor solder-wettability. A conventional method follows wherein the tie bars 13 are cut off, allowing the chip to be capable of electric operation. With the device constructed as such, the process of plating the distant segments with a metal the wetting property for soldering thereof is poor may be eliminated.

Title: Diffusion treating method for semiconductor wafer
Inventor: NAKADA KIMIO
IPC: F02M25/08
Filed: 1981-01-27
Abstract: PURPOSE: To ensure the uniformity of a diffusion layer formed through a throw in-out system while preventing the generation of thermal strain by setting temperature in the vicinity of a wafer inserting port in a diffusion oven at temperature higher than a central section in the oven only within a predetermined range of area.  
     CONSTITUTION: The temperaure of a soaking zone 1c of the diffusion oven 1 with an impurity gas supply pipe 1a is set previously at a prescribed diffusion temperature (such as 1,150°C), and a wafer 2 placed on a boat 3 is inserted from the inserting port 1b at low speed. The boat 3 is pulled out at low speed after an impurity is introduced into the oven and diffusion treatment for a fixed time is completed, but the temperature in the vicinity of the inserting port 1b of the diffusion oven 1 is set beforehand at the temperature higher than the soaking zone 1c by 5W15°C. Accordingly, the sheet resistance and the depth of joining of the diffusion layer can be formed equally while uniformity can be ensured even when the time of insertion and pulling out is comparatively short, and the generation of thermal strain in a diffusion region can be prevented.

Title: Exchange control system
Inventor: OTSUKA MASAYUKI
IPC: H04Q3/545
Filed: 1989-01-19
Abstract: PURPOSE:To attain impartial security of an outgoing line to the user independently of degree of local congestion of the incoming processing by sending a call setting to the outgoing side immediately when the call setting is received. CONSTITUTION:A call from an incoming line is realized as the transmission of a call setting message to an exchange and the message is fetched for the incoming processing of the exchange. On the other hand, the exchange sends the call setting to a network at the outgoing side and sends the call setting reception message to the incoming line succeedingly. On the other hand, the network side sends the call setting reception message to the exchange corresponding to the call setting. The exchange sets the internal path succeedingly with respect to the message reception. Thus, the chance of securing the outgoing line is given impartially to the user independently of the degree of congestion of the incoming processing.

IPC: D01H9/18
Filed: 1983-01-26
Abstract: PURPOSE:To improve the operation efficiency of a spinning machinery, by driving the package transfer conveyor placed at the center of the spinning machinery frame under specific condition according to the number count of the spun yarn. CONSTITUTION:In the case of spinning a spun yarn having small yarn number count which necessitates a long time for forming a full package, the package transfer conveyor 17 is usually stopped. When the auto-doffer 20 reaches the position corresponding to the full package, and if there is no package at the corresponding position on the conveyor 17, the doffing operation is carried out, and if there is a package P, the doffing is retained and the auto-doffer 20 is made to continue the running. In the case of spinning a yarn having large yarn number count necessitating a short time for the formation of full package, the conveyor 17 is driven constantly. When there is no package P at the position corresponding to the full package in the doffing with the auto-doffer 20, the conveyor 17 is temporally stopped to carry out the doffing, and if there is a package P, the conveyor is driven until it reaches a position free from package P, when the doffing is carried out.
